VEHICLE CHARGING SYSTEM

To provide a vehicle charging system capable of distributing surplus of photovoltaic generation power in addition to commercial power to vehicle charging smoothly.SOLUTION: A charging control unit has a charging control master unit 2 for controlling supply surplus of commercial power and photovoltaic generation power to a charger, and a plurality of charging control slave units 3 installed per charger and controlling current which a charger of a connection destination supplies to a vehicle. The charging control master unit 2 includes a second measuring unit 22 for monitoring surplus power of the photovoltaic generation power, a communication unit 25 for simultaneously informing surplus power information to each charging control slave unit 3 when the surplus power is generated, and a master unit CPU 26 for managing current supplied to each charger 4. When a new vehicle 5 is connected to the charger 4 during vehicle charging in the absence of the surplus power, charging current of a vehicle 5 which is being charged already is reduced by a predetermined amount, and the reduced current is supplied to the new vehicle 5.SELECTED DRAWING: Figure 1 【課題】 商用電力に加えて太陽光発電電力の余剰分も車両充電にスムーズに振り分けできる車両充電システムを提供する。【解決手段】 充電制御部は商用電力及び太陽光発電電力の余剰分の充電器への供給を制御する充電制御親機２と、充電器毎に設置されて、接続先の充電器が車両へ供給する電流を制御する複数の充電制御子機３とを有し、充電制御親機２は太陽光発電電力の余剰電力を監視する第２計測部２２と、余剰電力が発生したら各充電制御子機３に余剰電力情報を一斉通知する通信部２５と、各充電器４へ供給する電流を管理する親機ＣＰＵ２６とを備え、余剰電力が無い状態で車両充電中に新規車両５が充電器４に接続されたら、既に充電中の車両５の充電電流を一定量削減し、削減した電流を新規車両５に供給させる。【選択図】 図１
